300ci I-6 identification
I have found an I-6 engine for sale, out of vehicle, seller says it's a 300Ci. What is the easiest visual way to make sure the it is a 300? Are the valve covers different? Water pumps? Etc?
Also, this engine has no transmission attached. Can an AOD automatic be installed behind it? I think I have info on C-4's installed, but I'd like the o/d feature for better mileage, etc.
THANX in advance for educating me!!

Enjoy exploring FTE.
It'll be a blast.
You'll find a truckload of information, and meet some good people here, that'll help you out.
Enjoy, and welcome to FTE.
BTW, what part of Ca. are you in?

Ok, you're stretching my brain cells, but I used to own a 240-6. The only way to tell the difference externally is the crank pulley. From what I have heard, the crank pulley has an extra groove on it. Unfortunately, I cannot remember which has the extra grove, the 300 or the 240. Common sense tells me it should be the 300, but I'm not sure. If you don't get the answer in the inline six group, ask the Jegs.com site. http://www.jegs.com/webapp/wcs/store...10001_10002_-1
Or, you might try http://fordsix.com/forum/viewforum.p...e4f4b4ce70c4fd
Good luck, Jag

The ID number will lead to the years the damper was used.
No 240's after 1974.
Prior to 1975, if the damper has one or two pulley grooves (sheeves) it's a 240.

Ppl confuse the terms casting and engineering numbers. Casting numbers on blocks, heads, trans cases, etc. Other parts (electrical/fuel/steering/etc) carry Ford engineering numbers.
Casting numbers do not lead to actual Ford part numbers, but engineering numbers do.
D1VE-6015-AB, for example is the casting number for a 429/460 bare block. All I can tell you is it was used from 1971 thru early 1979 (actual cut off day/month unknown). There are at least 4 different finished blocks that derive from this casting number.
A 240/300 damper has (among others) Ford engineering numbers of: D8TE-6316-AA or C5TE-6312-AA

OK, stretching my mind a bit - I would measure the stroke. I am sure everyone is correct about the number of groves on the balancer, however, if any belt driven accessory was ever added to the truck that was the first thing changed.
Also, the 300 was a more heavy duty industrial/truck motor that had a lower compression ratio. If you look at the horsepower ratings the 240 with the higher compression ratio was almost as good. I don't remember a lot of difference between the two in driving, except the 300 got worse mileage.

Bore and stroke measurement will give you the accurate information....The motor might have been bored out. I have a 300 in my 4x4...great torque, but that also comes with the cam and tranny. Is a gas guzzler, but has taken me out of many tight spots.

I didn't look past 1979 to see what 1980/91's used. Microfiche slides are hard on the eyes.
Today has been a banner day...lotsa questions that can only be answered by staring at those D slides.
